Did you use an ACDelco switch?

Did you do the adjustment procedure for a new brake light switch?

No we used duralast for it. Adjustment procedure?

When installing a new brake light switch, you must use your hand to push the brake pedal forward, then without releasing the pedal - pull the pedal rearward, then release.

This adjusts and sets the plunger for the switch, which activates the brake lights (and allows them to turn off when the pedal is released by your foot).
